Prusa i3 Aluminium - Z Axis threaded rods
Posted: Sun Feb 28, 2016 5:29 pm
I'll start by saying this is my first 3d printer, and this is the first time I'm posting here.
I have a Geeetech Prusa i3 Aluminium.
I'm getting quite decent print quality + some terrible z banding. I pulled the z supports off and ran the head up and down. One of my threaded rods seems to move in large circles at the top where the other moves in a small circle.
The brass bush on the "wobbly" side is quite tight where the side that doesn't move around a lot can actually be wobbled in the bush itself.
I did a print of a calibration cube with no Z supports and it came out much better than with the Z supports on.
Has anyone created a part that does not hold the threaded bars in place for this printer?
Is there anything else that you would recommend to try and resolve this issue?
I found one on thingiverse for geeetech prusa i3 but it didn't fit this printer
